Abstract: PURPOSE:To recover efficiently unfiltered components, to simplify the structure of the apparatus, and to reduce the cost by providing a liquid nozzle for recovering the unfiltered components on the downstream side of an original liquid supply part oppositely to a filter cloth. CONSTITUTION:The original liquid contg. solid and liquid components is supplied over a filter cloth 1 from an original liquid supply tank 6. The greater part of the liquid component in the supplied original liquid is passed through the filter cloth 1 by gravity or a decompressing action given by a filtrate receiving tank 7, and collected in the filtrate receiving tank 7. The liquid component collected in the filtrate receiving tank 7 is discharged to the outside of the filter from a discharge port 17 of a seal pot 11. The so-called unfiltered component which does not pass through the filter cloth 1 is recovered from the surface of the filter cloth 1 by spouting the semifluid unfiltered component in a solid component receiving tank 10 from a recovery nozzle 8, and collected in the solid component receiving tank 10. The filter cloth 1 is passed through the positions of a drain roll 9 and a washing nozzle 14, and used again for the filtration.

Abstract: PURPOSE:To improve the solid-liq. separation capacity of the title separator by washing off the cake collected by the drum filter cloth with a spray from the outside of the filter drum, recovering the cake in a hopper in the drum, and specifying the elongation percentage of the filter cloth. CONSTITUTION:A liq. for recovering the cake collected on the filter cloth 20 is injected toward the filter cloth 20 from the spraying means 25 and 27 arranged outside the filter drum 14 in opposition to the filter cloth 20. The cake washed off by the recovering liq. is recovered in the recovery hopper means 29 and 30 provided in the drum 14. When the elongation percentage Ts of the filter cloth is defined as Ts=[(X-200)/200]X100, the Ts is controlled to at least 1.0%. In the equation, X is the distance between the two points of the test cloth cut out from the filter cloth material and having 250mm length and 30mm width when the load of 12kqf is applied to the test cloth and kept for 90 min, the two points are previously marked under the conditions where the initial load of 100gf is applied on the test cloth, and the distance is controlled to 200mm.

Abstract: PURPOSE:To secure a stable operative condition over a long period of time, by eliminating the contamination of the titled apparatus by the solid-containing liquid brought to an excessive supply state by the lowering in the function of filter cloth. CONSTITUTION:The titled separation apparatus is equipped with a solid-containing liquid discharge means consisting of a solid-containing liquid level adjusting tank 9 having a slid-containing liquid flooding weir 8 higher than a slid-containing liquid supply flooding weir 7, a solid-containing liquid discharge tank 14 connected to the above mentioned solid-containing liquid level adjusting tank 9 in the side of the above mentioned solid-containing liquid discharge flooding weir 8 and a solid-containing liquid discharge pipe. As a result, when the treatment capacit of the solid-containing liquid becomes low by the lowering in the function of filter cloth 1, the level of the solid-containing liquid in the solid-containing liquid level adjusting tank 9 rises. Then, the solid-containing liquid is flooded from the discharge flooding weir 8 to be flowed in the solid-containing liquid discharge tank 14 and the flowed out of the apparatus from the discharge pipe 13 of said discharge tank 14. Therefore, even if the solid-containing liquid is excessively supplied and flooded over the solid-containing liquid level adjusting tank 9, the contamination of the apparatus thereby is prevented.

CONSTITUTION:A solid-liduid mixture 6 is supplied to filter cloth 1 running in an endless state toward a direction shown by the arrow and the liquid component thereof is collected in a filtrate receiving tank 8 through the filter cloth 1 by gravity and vacuum suction action applied to said tank 8. In the next step, the liquid component in the tank 8 is discharged out of a dehydrator from a discharge port 9 and the component on the filter cloth 1 is carried between a transfer drum 14 and a squeeze roll 15 with the running of the filter cloth 1 to obtain a solid component. Subsequently, the surface of the filter cloth 1 is washed by water spray nozzles 17, 18 and the liquid component due to washing is further squeezed off by a drain roll 9 to again subject the filter cloth 1 to dehydration. In this case, the suction port 7 of a vacuum suction part is formed into a shape of which the width is increased in the running direction of the filter cloth 1 and a plurality of filter cloth guide rolls 10 are arranged to the suction port 7 so as to be matched with the aforementioned shape of an unfolded fan.
